Adhivasa-kirtanas mark the opening of a festival, occuring anywhere from a few days up to a month before the actual event. As festivals come in two flavors, the ananda-utsavas or festivals of joy, and the viraha-utsavas or festivals of separation, so there are distinct songs. In the tradition at Radha-kunda, all adhivasas begin with the Jayare Jayare Gaura song. Festivals of joy conclude with Age Rambha Aropana, and festivals of separation with Eka Adhivasa Ani. The adhivasa-songs describe the assembling of Sri Chaitanya, Nityananda and Advaita along with their companions for a celebration featuring the maha-yajna, or the great sacrifice, of sankirtan - congregational chanting of Krishna's names.
